| Know before using | The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review. | A profile, proposal, match, or escrow status does not establish factory ownership, identity, capacity, workmanship, quality systems, labour or chemical compliance, delivery performance, contract enforceability, or project fit. Verify the legal and production entities, references, site and subcontracting, samples, compliance evidence, specifications, terms, and remedies directly. | The record does not validate every size or user, prove bulk conformity, prescribe universal defect classes or AQL, replace testing or inspection, or establish compliance. |

| What the source establishes | The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments. | Sewport's current brand workflow starts with an account and guided project enquiry, then exposes proposals from garment factories and production specialists. The platform tells brands to compare profiles, portfolios, location, price, and communication, then record service, delivery, payment, and contract terms in a formal proposal. Its service-provider workflow includes factories, sample studios, pattern cutters, tech-pack makers, sourcing specialists, and material suppliers, with optional split-payment escrow. | The record applies version and lot controls from textile testing plus current ISO and ASQ acceptance-sampling boundaries to separate sample approval from bulk release. |
